INTAKE MANIFOLD UPGRADES ARE A MUST FOR LARGER CARBURETORS. IT DOESN'T MAKE SENSE TO INSTALL A LARGE CARBURETOR ONLY TO HAVE ITS FLOW RESTRICTED BY THE MANIFOLD. LARGER MANIFOLDS CAN MAKE A NOTICEABLE POWER INCREASE ON THEIR OWN, AND PROVIDE A CHOICE OPTION OVER THE STANDARD RUBBER MANIFOLDS. LONG LASTING PARTS, AND MORE POWER. ITS WIN-WIN.
